What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Florida has 1,640 active community water systems, 32% of the state's 5,197 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,996 Florida systems (96%) list groundwater as their primary source.
Who owns and regulates Port of the Islands?
EPA lists Port of the Islands as privately owned. The FL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 29 of the 45 active systems in Collier County (64%) are also privately owned.
Does Port of the Islands have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in November 2025. The violations listed here began between January 2022 and November 2025. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is E. coli (2 of them). EPA lists 9 as resolved, 2 as unaddressed and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
